StarWind Virtual Tape Library

StarWind VTL helps businesses to eliminate their costly tape backup processes while meeting regulatory data archival and retention requirements using on-premises Virtual Tape Libraries with cloud and object storage tier. Protect your backups from ransomware by keeping them air gapped on virtual tapes. Replicate and tier your backups to AWS, Azure, or any other public cloud to maximize storage cost-efficiency and security. Finally, use any industry-standard object storage array for flexibly scaling the local storage.

Archival and vaulting, another company’s pain, became faster and not that tedious and expensive thanks to StarWind. Double Fine automated their media asset backups while keeping them within their grasp in B2 cloud storage. This approach turned out to be far more cost efficient than shipping LTO offsite.

SMB use case is aimed at organizations looking to leverage cloud storage to automate their backup and archival processes. VTL automates and replaces manual DR tape shipping and augments existing DR plan by offering both replication & tiering. StarWind can also help with migrating the data to the cloud using a hardware data migration tools like AWS Snowball or Backblaze Fireball.

Enterprise use case is suited for organizations looking to leverage both object storage and cloud storage to automate their backup, archival, and media asset management. Here VTL provides a cost efficient air gapped nearline storage for media assets that need to be kept on-premises. For backups and archives VTL automates and replaces manual DR tape shipping and augments existing DR plan by offering replication & tiering to both object and cloud storage. StarWind can also help with migrating the data to the cloud using a data migration solution from your cloud provider of choice.

Service Provider use case allows organizations to offer tape as a service (TaaS), repository as a service (RaaS), and backup as a service (BaaS) using cloud and object storage instead of physical LTO. Service provider licensing offers a convenient per-user payment system. In addition, customer data migration services are provided free of charge.

VTL Benefits


VTL integrates seamlessly and requires zero changes to the established backup and archival process. Support for data migration solutions like Amazon Snowball, Azure Data Box, Backblaze Fireball, and others makes the process streamlined.


VTL automates and secures offsite backup and archival by eliminating human process and the need to ship physical tapes offsite. Data storage reliability is also higher with the ability to select geo-redundant storage with individual FTT levels.

Return of Investment

VTL is up to 10 times faster than LTO. It's also less expensive to operate and maintain than LTO. With added cloud and object storage support you get a storage system that scales to your needs and becomes more and more cost efficient over time.

VTL Features

Cloud Storage Support

StarWind VTL transparently extends existing on-premises backup storage pools to Azure, AWS or other public cloud storage services. This serves two purposes. First, organizations can transparently scale up storage capacity without purchasing any extra hardware. Second, public cloud storage offers the most appealing $/GB rate for long-term data archival.

On-premises S3 Object Storage Support

StarWind VTL dramatically simplifies storage management for organizations by interconnecting isolated storage silos. It allows using any industry-standard object storage arrays to expand the local storage pools. This way VTL unifies storage management and automates organization’s data flow between primary backup storage, on-premises object storage, and public cloud storage.

Ransomware Protection

Ransomware can't encrypt tape libraries so virtual tape is a safer backup repository compared to NAS or SAN. Additional copies in Amazon S3 and Glacier deliver complete data security even if the entire on-premises infrastructure is compromised.

StarWind Web-based Management

StarWind Web-based Management provides system administrators with the ability to access and manage their StarWind storage infrastructure via HTML5 web console from any location. This functionality delivers full control over storage-related operations from PC, Android, iOS or Windows mobile devices.

Scale-Up and Scale-Out

StarWind VTL allows both scale-up and scale-out architectures. Capacity is transparently increased by local object storage and public cloud storage. Adding more VTL instances scales the performance and shrinks the backup window by running multiple parallel backup operations.
